I'm not 100% sure this is actually word-for-word, but alas. "In a presentation at Ubuntu Developer Summit currently going on in Denmark, Drew Bliss from Valve said that Linux is more viable than Windows 8 for gaming. Windows 8 ships with its own app store and it is moving away from an open platform model." I feel like a broken record by now but here we go again: keep an eye on Valve, even if you're not into games. This is the company pushing NVIDIA and AMD to improve their Linux support, with enough clout and name to actually get stuff done. Valve doesn't mess around.

You're absolutely right technically! Although it's maybe a little disingenuous to be so strongly dismissive (in this context) of the Windows RT side of the Windows 8 coin though.

Only because a lot of people's thought process regarding Windows gaming won't immediately differentiate between Windows 8 x86 and Windows(8) RT - and that combined with Microsoft's push for Metro and the fact that x86/desktop applications will therefore have no place in the Metro App Store means effectively that WinRT tablets and notebooks is thereby a market (a market in terms of Mindshare I mean really, not technically obviously!) which Valve/Steam might have expected to be a part of but in reality isn't and won't be.

It probably feels like being pushed-out of Window's future a little bit (whether that's intentional or not!)
